Hi Mark,

The extra stringers on the back deck are mostly for adding strength for getting into and out of the cockpit. No reason that I know of to add strength to the rear deck for rolling. I've not done one of Tom's folders but have done several rigid wood frames of his (prefer working in wood) and I always put stringers on the rear deck to stiffen it, usually two, one per side. There's a frame right behind the cockpit on all of his designs, the combination of that frame and the two stringers makes the stern deck quite strong. Of course mine are positioned further inboard than the one in the picture.
